Abstract: A mesh network system adapted for a wireless access point includes multiple mesh network nodes, which are a root node, relay nodes, and leaf nodes. The root node is communicatively connected to the wireless access point. The relay nodes and the leaf nodes are configured to receive a downlink message having a downlink destination address. When one of the relay nodes that receives the downlink message determines that the downlink destination address fails to match its mesh network address, the relay node queries a routing table to find a next-hop node address directing to the downlink destination address and forwards the downlink message to the mesh network node corresponding to the next-hop node address. When one of the leaf nodes that receives the downlink message determines that the downlink destination address fails to match its mesh network address, the leaf node discards the downlink message.

Abstract: A first network device wirelessly transmits announcement messages in quick succession over multiple channels that represent normal operating channels of other network devices. The other network devices receive one of the announcement messages over their respective operating channels, and then send a message to one or more servers indicating that one of the announcement messages has been received. Various parameters and information related to the received announcement message, such as RSSI, SNR, and the contents of the announcement message, are included in the message sent to the one or more servers by each of the other network devices. The one or more servers then incorporate information in the messages sent from the other network devices into a network connectivity graph or table.

Abstract: A communications node of a multi-node communications network is disclosed. In embodiments, the communications node includes a communications interface and controller. The controller transitions the clustering status of the communications node to a clusterhead node status. The clusterhead node identifies a cluster of neighboring nodes with which it is in communication by transmitting hello messages identifying the clusterhead node and its status but omitting a one-hop neighbor list. The clusterhead node refines link discovery to the nodes of the multi-node communications network by flooding the network (e.g., via its cluster of neighboring nodes) with routing status messages, which network nodes not part of the dominating set of clusterhead nodes are restricted from sending.

Abstract: Systems and methods of reducing power consumption associated with paging or cDRX mode are described. A wake-up receiver (WUR) wakes up from an idle mode or cDRX state. Whether a wake-up signal (WUS) has been received by the WUR is determined. The WUS is a low-complexity signal that is less complicated than a PDCCH or PDSCH and is repeated multiple times at resource elements as indicated in a configuration from an eNB. If received, a baseband transceiver wakes up for reception of a PDCCH for the UE in a PO when the UE is in the idle mode or a PDSCH for the UE when the UE is in the cDRX state.

Abstract: The proposal concerns a method of adaptive route selection in a node of a wireless mesh communication network. Such method is based on the Reinforcement Learning-based adaptive routing scheme. The proposal includes the idea of estimating initial reward values for the path discovery phase in dependence of the signal strength of the received signal and the number of hops the received route request message (RREQ) or route reply message (RREP) experienced during traversing in the network. Further improvements concern the idea of a feedback reward calculation for the routing absent the path discovery process as well as an improved method of route selection based on calculation of a temperature parameter for a Gibbs-Boltzmann distribution, which allows a dynamic adjustment of the node selection probabilities. Another improvement concerns a part of the reward function calculation, related to an exponential fallback mechanism on packet loss events.
